Defensive publication

ABSTRACT

A BITUMINOUS COATING COMPOSITION PREPARED FROM BITUMINOUS MATERIAL, POLYISOCYANATES, POLYEPOXIDES AND POLYOLS WHEREIN AT LEAST A PORTION OF SAID POLYOL IS A HYDROXYL TERMINATED POLYBUTADUEBE. THE RESULTANT COATINGS ARE EXTREMELY FLEXIBLE AND SHOW IMPROVED IMPACT RESISTANCE AS WELL AS RESISTANCE TO CHEMICALS AND WATER THAN RECOGNIZED EPOXY SYSTEMS. WHEN APPLIED TO METALS, WOOD, MASONRY AND CONCRETE, THE COATINGS PROVIDE CORROSION RESISTANCE.
